Designing PID algorithm is accomplished with a compromise to result in an overall system responds with acceptable levels of stability, response fastness, smoothness and costs. Various PID design methodologies and expressions have been introduced in text and literature,each has its advantages, disadvantages and limitations. In the present work, a new, efficient, simple, easy to apply and linear expressions for PID algorithmP-. PI, PD, and PID modes design are derived and presented. Expressions are derived based on relating parameters of both controller and plant. The expressions are intended to control the behavior of second order systems and approximated as such systems, such that it responds with acceptable stability level, minimum possible overshoot, oscillations and steady state error. To further improve the resulted response, only one tuning parameter α, is introduced To test, analyze, and evaluate the design expressions, MATLAB/Simulink software was used. A simulation model was built by integrating the next sub-models; PID control algorithm modes, drive with limitation and saturation blocks, sensor, desired output signal generator and finally various forms of second order systems. The simulation model was developed and refined to be as close as possible to real life conditions and processing. Studying the recorded testing, graphical and numerical results show that the suggested expressions are being simple and easy to apply, and also efficient in providing better control over controlled system’s behavior in terms of response measures and performance indices.Moreover, expressions are efficient to speed up response and eliminate or reduce overshoot, rise time and settling time. Studying results show that, the overall system responds with acceptable fast response, in most cases without overshoot, oscillation and with minimum steady state error and better ISE and IAE indices values.","PeriodicalId":13763,"journal":{"name":"International Journal of Applied Science and Engineering Research","volume":"49 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86082527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, NOMA faces several challenges that still need to be solved optimally. Deep learning algorithms have been proposed as a potential solution to address these challenges. This review provides an overview of the use of deep learning algorithms to optimize NOMA performance in 5G networks. An investigation is conducted on how deep learning methods are applied in NOMA systems for resource allocation, channel estimation and detection, successive interference cancellation, and user clustering.They can learn optimal user clustering, optimal allocation, and interference alignment strategies, eventually boosting the network performance. In addition, deep learning algorithms can learn the complex relationships between the transmitted symbols and the received signal, leading to accurate detection of the superimposed signals. Opportunities and challenges in NOMA can be identified based on existing research showing how applying deep learning algorithms is better than conventional approaches. The main contribution of this review is to provide insights into the potential of deep learning algorithms to remarkably improve NOMA performance in 5G networks. This article is also a valuable resource for researchers and practitioners interested in using deep learning algorithms for NOMA in 5G networks.","PeriodicalId":13763,"journal":{"name":"International Journal of Applied Science and Engineering Research","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85566233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Dynamic Learning Program (DLP), which is based on activity-based multidomain learning, requires students to work independently in order to read the concept notes and complete the exercises before the lesson is discussed and explained. This way, students can independently discover and understand the lesson. Students learn more by acting than by merely listening, according to the theory. This study utilized descriptive statistics to determine the students’ level of knowledge, attitudes, beliefs, and academic performance. The Pearson Product Moment Correlation Coefficient and multiple-linear regression were both used to determine which variable or variables, alone or in combination, best predict students' academic achievement in mathematics. This study was conducted at Pangantucan Community High School, Pangantucan, and Bukidnon. The respondents of this study were the 120 grade-11 students who were exposed to Dynamic Learning Program. The results of this study shown that the students are highly knowledgeable about DLP, and this teaching methodology was highly accepted and valued by the PCHS students. The academic performance of the students is above the average, it implies that the students who were exposed to dynamic learning programs have a good performance in their mathematics subject. However, the Pearson product-moment correlation showed that the student’s knowledge, attitude, and beliefs on Dynamic learning Program was not significantly correlated to their academic performance. And also, in the multiple-linear regression results showed that students’ knowledge, attitudes, and beliefs on dynamic learning couldn’t predict the academic performance of the students in their mathematics subject during modular distance learning modality.","PeriodicalId":13763,"journal":{"name":"International Journal of Applied Science and Engineering Research","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80379913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, it examined the profile, marketing practices, entrepreneurial orientation, access to finance, and business performance of these enterprises. The study used responses from 417 micro-enterprises selected through stratified random sampling from the provinces of Bukidnon, Camiguin, Lanao del Norte, Misamis Occidental and Misamis Oriental. A descriptivecorrelational research design was employed to attain the objectives of the study. More than half of micro-enterprises employed 1-4 employees and undertook their business for not more than five years. Marketing practices are implemented most of the time. Their entrepreneurial orientation was high, access to finance was moderate to great, and their business performance for the last three years was average to good. The aggregate multinomial logistic regression analysis reveals that among the variables used in the study, business age, marketing practices, entrepreneurial orientation, and access to finance significantly influence the business performance of micro-enterprises. The multinomial logistic regression per industry analysis yields a different result. In merchandising industry sector, marketing practices, business age, and access to finance influence substantially business performance. In the service industry sector, entrepreneurial orientation, business age, and access to finance significantly influence business performance.","PeriodicalId":13763,"journal":{"name":"International Journal of Applied Science and Engineering Research","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83639687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Food and Nutrition play a major role in the prevention of almost all diseases and promotion of health. Unfortunately at the global level, India is being placed among the highest ranked countries on the basis of number of malnourished children1. Childhood is a crucial period where we need to pay some extra attention for the nutritional needs and nutritional care of a child, as it acts as a strong pillar for his/her growth and development and prevention of malnutrition. Despite many medical advances over the past 20 years, the prevalence of malnutrition among hospitalized children has not decreased. Since the staff nurses spent more time with patients than any other healthcare workers and the patient recovery is greatly affected by the quality of care these nurses provide to their patients in all the aspects of care, including the nutritional aspect. Present study was conducted to assess the Nurses’ Knowledge, Attitude and Practice towards nutritional care of the hospitalized children, in order to ensure quality nutritional care for hospitalized children who are at risk of developing malnutrition or who are already victims of it. A nonexperimental descriptive research design was adopted to carry out the present study on a sample of 40 staff nurses working at a Tertiary care hospital of Karnataka by administering MKAP questionnaire. The results of the study showed that majority of the staff nurses 28(70%) had average knowledge and neutral attitude regarding malnutrition and nutritional care among hospitalized children , while as 7(17.5%) had good knowledge and positive attitude and 5( 12.5%) of them had poor knowledge and negative attitude regarding malnutrition and nutritional care among hospitalized children. The majority of the staff nurses 25(62.5%) showed neutral practice regarding malnutrition and nutritional care among hospitalized children, while as 10 (25%) showed beneficial practice and 5 (12.5%) of them showed non-beneficial practice regarding malnutrition and nutritional care among hospitalized children. In the present study the association of Levels of KAP with demographic characteristics of the staff nurses was calculated by using chi-square test and no association was found between the two except for gender.
